A Method for Microscopic Examination of Printed Matter

A rapid method for electron microscopic examination of blood cells.

A method is described whereby the time required for the processing of white blood cells for electron microscopy can be shortened from 36 to 3 1/2 hours. Because cells of the peripheral blood are not attached to each other, fixation, dehydration, and infiltration of the embedding medium is more rapid. This makes it possible for clinicians to use fine structural data for diagnosis as illustrated ...

A method for preparing permanent stained mounts of pathogenic fungi for microscopic examination.

Many pathogenic fungi may be recognized grossly by their appearance in culture. The more definitive method of identification, however, is through microscopic examination of the structures on which classification depends: the spores and the sporebearing apparatus. The simplest method of accomplishing this is to tease a small fragment of mycelium out of the culture and crush it under a cover slip...

Application of High Performance Thin Layer Chromatography in Examination of Magenta Coloured Printed Matter

The technique of High Performance Thin Layer Chromatography was utilized to separate the components of magenta colour inkjet printer ink. An attempt has been done to develop a protocol to examine and opine on the issue of identification of printer from which a document was printed.

The Microscopic Examination of Milk

The microscope has been used to observe and count bacteria and somatic cells in raw milk since the early 1900’s. It has proven to be a valuable tool to the dairy industry. The milk smear procedure in use today is outlined in detail in the most recent edition of Standard Methods for the Examination of Dairy Products (i.e., SMEDP, 17 ed) and other references. For somatic cell counting, the Direct...
